IVOLFF FLUSHlNG-TANK FOR WAT ER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 442,80 4, datedDecember 16, 1890.

Application filed April 12, 1889. Serial No. 306,924. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES G1ELoW",.a citizen of the United States,residingin Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Flushing-Tanks forater-Closets, of which the following is a specification.

My invention relates to overhead cisterns or tanks used for flushingwater-closets.

The object of my invention is to provide means for preventing thesomewhat disagreeable and objectionable gurgling noise which attends theuse of these overhead tanks, especially at the last end of thewater-discharge.

My invention consists in the means I employ to accomplish thisresult-that is to say, in providing the tank ortheflushingor measuringcompartment thereof, if it is divided, as usual, into two compartments,with a cover having a limited opening for the admission of air, wherebythe violence of the final discharging of the water and the noiseoccasioned thereby may be prevented.

It also consists inthe novel devices and novel combinations of parts anddevices herein shown and described, and more particularly pointed out inthe claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is aplan view of a device embodying my invention, and Fig. 2 isa section on line 2 2 of Fig. 1.

In said drawings, Arepresents the tank or cistern; B, the measuring offlushing compartment thereof; C, the water-inlet or supply pipefurnished with a float-valve Cof any ordinary or usual construction; D,the discharge or flushing pipe leading to the water-closet bowl, forexample; D, the discharge-valve, and D the lever for operating it. Thefiushiug-valveD maybe of any ordinary orknown construction; but I haveshown in the drawings and prefer to employ the now well-knownsiphon-plunger form of valve, so that the valve requires to be onlymomentarily open ed to start the siphon.

The partition to, between the compartments A and B, is furnished with asmall opening or passage a, so that after the compartment B is emptiedit may refill from the cistern A.

The compartment or flushing-tank proper B is closed at the top by acover B, preferably of sheet metal, having an opening b for thesiphon-plunger D to project through, and in which the plunger fitssomewhat loosely, so as to leave a limited passage around the plungerfor the admission of air to the closed tank B when the valve D is raisedor open. As the opening a between the cistern A and the tank B is alsoof limited area, the violence of the discharge of water through theflushing-pipe D will be controlled by the comparatively small openingsthrough which air or water may enter the closed tank B to replace thewater flowing out through the flushingpipe D. By thus simply providingthe overhead cistern or the discharging-compartment thereof, if it isdivided into two compartments, with a closed cover having a passage oflimited size for the admission of air, I prevent the disagreeable noiseheretofore incident to the use of these overhead flushing-tanks.

The opening I) in the cover 13 is surrrounded with a collar 1) tore-enforce the tin or sheet metal of which the cover B is composed. The

' collar or ring I), being secured by screws to the cover B, also servesas a guide for the plunger D. The air-inlet around the plunger D and thewater-inlet a are of small area as compared with the discharge-pipe D.

The opening I) in the cover Bis made large enough to permit the removaland insertion of the si phon-plunger, the collar 1) serving to somewhatcontract the opening and being removably secured to the arms B by thescrews b The water in the compartment B is discharged more rapidly thanit enters through the opening, a, and the water in the main tank A beingabove this opening a no air I enters therefrom, and the limitedair-supply at Z) is not sufficient to interfere with the comparativenoiseless service of the water through the opening d in thesiphon-plunger; but the air is fed through this opening I) at thefinishing of the discharge gradually or in limited quantity to break thesiphon slowly.

I claim- '1. The combination of a cistern or tank A, having a closedcompartment B, its discharge- 3. The combination of a cistern or tank A,having closed compartment B, water-inlet a, discharge-pipe D, valve D,and an air-inlet to said closed compartment of small size compared withthe discharge-pipe, said air-inlet being open during the discharge ofWater from said compartment B, substantially as specified.
